When we first visited The Dental Anesthesia Center, my child was experiencing severe tooth pain and multiple cavities. Dr. Sean M. Thoms and his team demonstrated excellent care, promptly assessing the situation and deciding to treat his teeth the next day. They came early in the morning, professionally addressing the cavities and placing a crown. They also followed up by phone to ensure my child was doing well. My baby is now pain-free,happy ,smiling, and sleeping soundly. This is truly a world-class dental center with an exceptional, caring team. Highly recommended.

I cannot say enough wonderful things about The Dental Anesthesia Center and Dr. Thoms. My 7-year-old, who has autism, recently had dental work done here and the experience exceeded expectations. The staff was incredibly kind, patient, and understanding of his needs. They took the time to make him and us feel comfortable, never rushed, and explained everything. I am so grateful for this office and the team that made my son's dental care possible. I would recommend The Dental Anesthesia Center and Dr Thoms to any parent, especially those with children who have special needs. They truly go above and beyond. ❤️

My son has been a patient of Dr Michael Hoffman since he was 5 years old. He is now 21 years old. My son has diagnosis of autism spectrum disorder and therefore I am cautious of who I select as a treatment provider. Dr. Hoffman’s office is professional, kind and I know they have his best interest at heart. I highly recommend Dr. Hoffman and staff to anyone seeking dental care.
Response from the owner:Thank you for your kind words and recommendation! We truly appreciate your trust in our team over the years.

Understanding Novocaine Allergies and Why They Matter in Dentistry

For many patients, the fear of pain during dental procedures is managed with local anesthetics—commonly thought of as “Novocaine.” However, the term Novocaine (procaine) is often misused today, as it’s largely been replaced by safer and more effective agents like lidocaine, articaine, and mepivacaine. Still, the concern around allergic reactions remains valid, especially for individuals who have experienced symptoms such as swelling, itching, dizziness, or difficulty breathing after a dental injection. These symptoms can indicate a true allergy or a sensitivity to preservatives, sulfites, or other components in anesthetic solutions.

Understanding what causes these reactions is critical. True allergic reactions to modern amide-type anesthetics like lidocaine are extremely rare. Most adverse responses are due to additives (like epinephrine preservatives or latex in delivery devices), vasovagal responses (fainting from anxiety), or toxic reactions to high doses. Nonetheless, a careful dental plan is essential for any patient who suspects or knows they have a novocaine or anesthetic-related allergy. That’s where sedation dentistry becomes an important and often life-changing alternative.

How Sedation Dentistry Offers Safe, Allergy-Conscious Solutions

For patients with sensitivities to injectable anesthetics, sedation dentistry provides a safer, more controlled alternative. At The Dental Anesthesia Center in St. Louis, we specialize in custom-tailored sedation solutions that bypass the need for traditional local anesthetics when appropriate. These alternatives include oral sedation, IV sedation, and even general anesthesia, depending on the severity of the allergy and the complexity of the dental procedure.

For example, IV sedation allows us to use minimal, carefully monitored doses of sedatives while maintaining patient comfort and avoiding problematic substances altogether. General anesthesia, administered by a board-certified dentist anesthesiologist in a hospital-grade setting, ensures that the patient is entirely unconscious and feels no pain, without the need for local anesthetics if contraindicated. This is especially critical for patients who have both severe anxiety and known allergies.

We also use preservative-free local anesthetic options for those who are not allergic to the anesthetic agent itself, but to preservatives or additives commonly found in standard formulations. These options are explicitly sourced for sensitive patients and administered only after a thorough medical review.

Diagnostic Precautions: Confirming and Managing True Allergies

Before undergoing any dental treatment, patients with suspected novocaine allergies should undergo a medical evaluation, including a review of past reactions and, in some cases, an allergist-conducted skin test. At DAC, we collaborate with patients’ primary care physicians and allergists when needed to ensure that every step is safe and fully informed.

Our intake process involves a deep dive into the patient’s medical history, including previous dental experiences, current medications, and any adverse events. This risk assessment helps us determine whether the reaction was truly allergic or related to anxiety, preservatives, or even vasoconstrictors like epinephrine.

This diligence allows us to eliminate guesswork and ensure that patients receive exactly the care they need without compromise—no assumptions, no unnecessary exposure to allergens, and no preventable reactions.

Who Benefits Most from Sedation Alternatives?

While anyone with a known allergy to local anesthetics is an obvious candidate, the benefits of sedation dentistry extend far beyond allergy management. Patients with the following conditions often find sedation dentistry to be life-changing:

For these individuals, the ability to undergo treatment comfortably and safely—without risk of allergic reaction—can be the key to restoring both dental health and personal dignity.
